1. A testing apparatus for the detection of Legionella bacteria in a liquid sample, the apparatus comprising:
a sample tray defining a planar surface and a plurality of wells recessed relative to the planar surface, the sample tray formed from a sample tray material that is permeable, transparent, and non-toxic to Legionella bacteria; and
a lid member, including:
an adhesive layer formed from a first permeable material different from the sample tray material;
a breathable film layer disposed directly about the adhesive layer, the breathable film layer formed from a second permeable material different from the sample tray material and the first permeable material; and
a backing layer disposed directly about the breathable film layer,
wherein the adhesive layer is configured to transition from an unsealed configuration, wherein at least a portion of the adhesive layer is not adherable to the planar surface of the sample tray upon contact therewith, to a sealed configuration, wherein the adhesive layer is directly sealed to the planar surface of the sample tray, thereby sealing the lid member over the plurality of wells.
